Use proper power cord. Use only the power cord specified for this product and certified for the country of use. Do not use the
provided power cord for other products.
Use proper voltage setting. Before applying power, ensure that the line selector is in the proper position for the source being
used.
Ground the product. This product is grounded through the grounding conductor of the power cord. To avoid electric shock, the
grounding conductor must be connected to earth ground. Before making connections to the input or output terminals of the
product, ensure that the product is properly grounded. Do not disable the power cord grounding connection.
Ground the product. This product is indirectly grounded through the grounding conductor of the mainframe power cord. To
avoid electric shock, the grounding conductor must be connected to earth ground. Before making connections to the input or
output terminals of the product, ensure that the product is properly grounded. Do not disable the power cord grounding
connection.

position the equipment so that it is difficult to disconnect the power switch; it must remain accessible to the user at all times to
allow for quick disconnection if needed.
Power disconnect. The power cord disconnects the product from the power source. See instructions for the location. Do not
position the equipment so that it is difficult to operate the power cord; it must remain accessible to the user at all times to allow for
quick disconnection if needed.
Use proper AC adapter. Use only the AC adapter specified for this product.

Important safety information
Connect and disconnect properly. Do not connect or disconnect probes or test leads while they are connected to a voltage
source. Use only insulated voltage probes, test leads, and adapters supplied with the product, or indicated by Tektronix to be
suitable for the product.
Observe all terminal ratings. To avoid fire or shock hazard, observe all rating and markings on the product. Consult the product
manual for further ratings information before making connections to the product. Do not exceed the Measurement Category
(CAT) rating and voltage or current rating of the lowest rated individual component of a product, probe, or accessory. Use caution
when using 1:1 test leads because the probe tip voltage is directly transmitted to the product.
Observe all terminal ratings. To avoid fire or shock hazard, observe all rating and markings on the product. Consult the product
manual for further ratings information before making connections to the product.
Do not apply a potential to any terminal, including the common terminal, that exceeds the maximum rating of that terminal.
Do not float the common terminal above the rated voltage for that terminal.
The measurement terminals on this product are not rated for connection to mains or Category II, III, or IV circuits.
Do not operate without covers. Do not operate this product with covers or panels removed, or with the case open. Hazardous
voltage exposure is possible.
Avoid exposed circuitry. Do not touch exposed connections and components when power is present.
Do not operate with suspected failures. If you suspect that there is damage to this product, have it inspected by qualified
service personnel.
Disable the product if it is damaged. Do not use the product if it is damaged or operates incorrectly. If in doubt about safety of the
product, turn it off and disconnect the power cord. Clearly mark the product to prevent its further operation.
Before use, inspect voltage probes, test leads, and accessories for mechanical damage and replace when damaged. Do not use
probes or test leads if they are damaged, if there is exposed metal, or if a wear indicator shows.
Examine the exterior of the product before you use it. Look for cracks or missing pieces.
Use only specified replacement parts.
Replace batteries properly. Replace batteries only with the specified type and rating.
Recharge batteries properly. Recharge batteries for the recommended charge cycle only.
Use proper fuse. Use only the fuse type and rating specified for this product.
Wear eye protection. Wear eye protection if exposure to high-intensity rays or laser radiation exists.
Do not operate in wet/damp conditions. Be aware that condensation may occur if a unit is moved from a cold to a warm
environment.
Do not operate in an explosive atmosphere.
Keep product surfaces clean and dry. Remove the input signals before you clean the product.
Provide proper ventilation. Refer to the manual's installation instructions for details on installing the product so it has proper
ventilation.
Slots and openings are provided for ventilation and should never be covered or otherwise obstructed. Do not push objects into
any of the openings.
Provide a safe working environment. Always place the product in a location convenient for viewing the display and indicators.
Avoid improper or prolonged use of keyboards, pointers, and button pads. Improper or prolonged keyboard or pointer use may
result in serious injury.

Important safety information
Be sure your work area meets applicable ergonomic standards. Consult with an ergonomics professional to avoid stress injuries.
Use care when lifting and carrying the product. This product is provided with handles for lifting and carrying.
WARNING. The product is heavy. To reduce the risk of personal injury or damage to the device get help when lifting or carrying
the product.
WARNING. The product is heavy. Use a two-person lift or a mechanical aid.
Use only the Tektronix rackmount hardware specified for this product.
Probes and test leads
Before connecting probes or test leads, connect the power cord from the power connector to a properly grounded power outlet.
Keep fingers behind the finger guards on the probes.
Remove all probes, test leads and accessories that are not in use.
Use only correct Measurement Category (CAT), voltage, temperature, altitude, and amperage rated probes, test leads, and
adapters for any measurement.
Beware of high voltages. Understand the voltage ratings for the probe you are using and do not exceed those ratings. Two
ratings are important to know and understand:
■
The maximum measurement voltage from the probe tip to the probe reference lead.
■
The maximum floating voltage from the probe reference lead to earth ground.
These two voltage ratings depend on the probe and your application. Refer to the Specifications section of the manual for more
information.
WARNING. To prevent electrical shock, do not exceed the maximum measurement or maximum floating voltage for the
oscilloscope input BNC connector, probe tip, or probe reference lead.
Connect and disconnect properly. Connect the probe output to the measurement product before connecting the probe to the
circuit under test. Connect the probe reference lead to the circuit under test before connecting the probe input. Disconnect the
probe input and the probe reference lead from the circuit under test before disconnecting the probe from the measurement
product.
Connect and disconnect properly. De-energize the circuit under test before connecting or disconnecting the current probe.
Connect the probe reference lead to earth ground only.
Do not connect a current probe to any wire that carries voltages above the current probe voltage rating.
Inspect the probe and accessories. Before each use, inspect probe and accessories for damage (cuts, tears, or defects in the
probe body, accessories, or cable jacket). Do not use if damaged.
Ground-referenced oscilloscope use. Do not float the reference lead of this probe when using with ground-referenced
oscilloscopes. The reference lead must be connected to earth potential (0 V).
Floating measurement use. Do not float the reference lead of this probe above the rated float voltage.
